Exception for Trigonometry A

\[0.0 \le e \le 1\]

Math

\[\frac{e \cdot \sin v}{1 + e \cdot \cos v}\]

C

double f(double e, double v) {
        double r22998 = e;
        double r22999 = v;
        double r23000 = sin(r22999);
        double r23001 = r22998 * r23000;
        double r23002 = 1.0;
        double r23003 = cos(r22999);
        double r23004 = r22998 * r23003;
        double r23005 = r23002 + r23004;
        double r23006 = r23001 / r23005;
        return r23006;
}
